Specification of Letters Patent. Application filed February 18, 1907.Serial No. 358,154.

.. To all whom 'it may concern: I

Be it known that I, HARRY L. BRUCE, a citizen of the United States, andresident of Portland, in the county of Multnomah and State of Oregon,have invented a new and useful Process for Treatment of Fuel- Coke, ofwhich the following is a specification.

This invention consists in taking foundry-coke and filling the poresthereof with crude-oil so that it will readily ignite and continue toburn without requiring a strong draft.

It is well known that foundry-coke possesses highheating value, but itis a diflicult substance to keep burning, requiring a strong draftconstantly;

To make my improved fuel I take a quantity of the foundry-coke and placethe same in a receptacle filled with a mixture of crudeoil and water,and allow the coke to remain in the mixture until it has absorbed allthereof it will hold. I then remove the coke from the mixture and allowit to become sur: face dry, after which it is in condition to be shippedwhere wanted. In order to obtain the proper inter-mixture of crude-oiland water suflicient in quantity to saturate about thirty pounds offoundry coke, I-take eight pounds of oil and pour the same in sixteenpounds of water, heated to the boiling point, and thoroughly inter-mixthe two; the coke is then immersed in said inter-mixture, which is keptin a commingled state by con- .stant agitation during'such immersion;the

hot water and oil will continue in a suitable inter-mixture to beabsorbed in that state by the coke. The oil absorbed by the coke usual,the

continue to burn will impart to the latter the property of becoming moreeasily ignited, and the oil will also prevent the evaporation of theglobules of water contained in the pores of the coke; and after the oilin the pores of the coke has becomeignited, the water globules willinstantly be converted into a vapor, the gases ofwhich will stimulatethe more thorough ignition 0f the coke. The resultant substance, which Ifind convenient to call crudeoil coke, is'to be used in a furnace aboutas fire being readily started with kindlings.

After my crude oil coke has ignited it will freely, with a whitesmokeless fiame until both coke and the fluid held in suspension therebyhave been completely consumed, and it required only a little draft tokeep it going. I find that the crude-oil burns with great heat, and thatbesides it is very temperature at .less cost than obtained by burningeither the coke or crude-oil separately.

I claim: I Y

The process of treating coke, for the purpose mentioned, which consistsin immersing the same in a mixture of crude-oil and water,

said water being heated to boiling point to HARRY L. BRUCE.
